3. Install MariaDB

Run the following command to install MariaDB:

pacman -S mysql

As you may know, MariaDB is now officially the default implementation of MySQL in Arch Linux since 2013. So, you will be asked whether to install MariaDB or Percona server, just hit enter and then type “Y” and press enter again. The default selection i.e MariaDB will be installed on your Arch Linux.

Set MySQL/MariaDb root user password

As you may know, It is recommended to setup a password for database root user.

Run the following command to setup MariaDB root user password:

mysql_secure_installation

Sample output:

NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MariaDB
SERVERS IN PRODUCTION USE! PLEASE READ EACH STEP CAREFULLY!
In order to log into MariaDB to secure it, we'll need the current
password for the root user. If you've just installed MariaDB, and
you haven't set the root password yet, the password will be blank,
so you should just press enter here.
Enter current password for root (enter for none): ## Press Enter
OK, successfully used password, moving on...
Setting the root password ensures that nobody can log into the MariaDB
root user without the proper authorisation.
Set root password? [Y/n]## Press Enter
New password:## Enter password
Re-enter new password: ## Re-enter password
Password updated successfully!
Reloading privilege tables..
... Success!
By default, a MariaDB installation has an anonymous user, allowing anyone
to log into MariaDB without having to have a user account created for
them. This is intended only for testing, and to make the installation
go a bit smoother. You should remove them before moving into a
production environment.
Remove anonymous users? [Y/n]## Press Enter
... Success!
Normally, root should only be allowed to connect from 'localhost'. This
ensures that someone cannot guess at the root password from the network.
Disallow root login remotely? [Y/n]## Press Enter
... Success!
By default, MariaDB comes with a database named 'test' that anyone can
access. This is also intended only for testing, and should be removed
before moving into a production environment.
Remove test database and access to it? [Y/n]## Press Enter
- Dropping test database...
... Success!
- Removing privileges on test database...
... Success!
Reloading the privilege tables will ensure that all changes made so far
will take effect immediately.
Reload privilege tables now? [Y/n]## Press Enter
... Success!
Cleaning up...
All done! If you've completed all of the above steps, your MariaDB
installation should now be secure.
Thanks for using MariaDB!

MariaDB has been installed and ready to use.

4. Install PHP

To install PHP in Arch Linux, run:

pacman -S php-fpm

After PHP is installed, we need to tell Nginx to run PHP using php-fpm.
